An Oklahoma City police officer has been charged with second-degree murder in connection with the Nov. 15 death of a suicidal person.

According to court documents released Tuesday morning, Oklahoma City police Officer Keith Patrick Sweeney has been charged with second-degree murder, or in the alternative of first-degree manslaughter, in the death of Dustin Pigeon.

According to police, officers responded on Nov. 15 to a report of a person threatening suicide in the 1400 block of Southwest 20th Street. Police said that when officers arrived, Pigeon was holding a bottle of lighter fluid and a lighter, threatening to set himself on fire.

Police said an officer deployed a less-than-lethal bean bag shotgun, striking Pigeon in the left hip. Officer Sweeney discharged his duty weapon, hitting Pigeon multiple times, according to court documents.

Pigeon was pronounced dead at the scene, according to police.

Authorities said Pigeon was not armed and was not a threat to the officers when he was shot. After presenting the investigation to the Oklahoma County District Attorney's office, authorities determined that the use of deadly force by Sweeney against Pigeon was not justified.
